All of my Ellora's Cave titles are now up at Amazon in Kindle format. There are a couple of errors here and there on the listings, but those will be corrected soon. I'll have direct links up to all of the Kindle formats from my excerpt pages soon (next few days).
Also, one of my Changeling Press titles is in Kindle format. I think that's the only one which will be going up from that publisher, at least for now.
